Definitions

  • the invention relates to a continuous washing machine in accordance with the preamble of Claim 1 , as well as to a washing process used by such a continuous washing machine in accordance with the preamble of Claims 16 and 17 , respectively.
  • Continuous washing machines operate based on a pivoting or rotating washing principle.
  • the laundry transport is accomplished along the generated surface of the drum or through the center of the drum.
  • a continuous washing machine in accordance with the preamble of Patent Claim 1 has been known from document DE 199 41 073 A1.
  • the washing regions located next to each other in longitudinal direction of the drum are configured as washing chambers defined by discoidal dividing walls, said dividing walls being arranged in the drum perpendicular to the longitudinal axis of the drum and their exterior edges being welded to the drum.
  • central circular openings are provided in the dividing walls, each of said openings being provided upstream with a blade-like structure that also comprises a metal dividing baffle.
  • One disadvantage of this known continuous washing machine consists in that the material of the drum having, in particular, a length of several meters is subject to high mechanical loads, whereby the straight, planar dividing walls existing in this case do not result in any increase of the strength of the drum. Furthermore, the high mechanical load requires a comparably high strength of the material of the drum, thus leading to increased manufacturing costs, on the one hand, and to increased energy use for driving the drum, on the other hand.
  • Another disadvantage of the known continuous washing machine consists in that, while the laundry items are being passed from one chamber to the adjacent chamber through the opening or the transport channel in the corresponding dividing wall, the risk of an obstruction of the opening occurs.
  • This risk of obstruction is considerable if it is taken into consideration that the drum, as a rule, comprises a plurality of successive washing chambers in longitudinal direction of the drum and that the laundry items must therefore be passed through a plurality of openings during a single pass through the plant.
  • an Archimedean screw or worm is arranged in the drum that can be selectively rotated in one or the other direction, said screw or worm being non-rotationally connected to the drum and being connected in a fluid-tight manner to the inside of the drum along said drum's exterior edge.
  • the setup of this arrangement basically corresponds to that of a screw-tube conveyor.
  • Respectively one washing chamber is defined between two adjacent cants of a screw, thus corresponding to a washing chamber of the aforementioned prior art.
  • the drum, along with the screw is rotated by 360°, whereby, consistent with the known mode of operation of a screw-tube conveyor, the items of laundry lying in the treatment fluid, along with the treatment fluid, are advanced in conveying direction by a distance corresponding to the width of one washing chamber.
  • the drum, including the screw is intermittently moved in one and in the other direction, i.e., back and forth, and the required washing mechanics are thus generated.
  • the drum is imparted with particular structural rigidity, so that minimal material thicknesses are sufficient to achieve the necessary strength.
  • the object of the invention is to provide a continuous washing machine that displays particular mechanical stability, which largely avoids obstructions while the laundry items are conveyed and that, nevertheless, is capable of washing in a rotating manner. Also, a washing process suitable for this washing machine is to be provided.
  • this object is essentially achieved by a washing machine displaying the features in accordance with Claim 1 , as well as with a washing process in accordance with Claims 16 and 17 .
  • the continuous washing machine in accordance with the invention is characterized by great stability in that it is basically designed consistent with the principle of a screw-tube conveyor, whereby the worm or screw located in the drum and connected to the drum provides mechanical stability for the overall design, so that, with the use of a relatively light-weight design, it is still possible to achieve the necessary mechanical stability and that relatively low driving energy is sufficient during operation.
  • the inventive continuous washing machine it is possible to virtually exclude the risk of obstruction while the laundry items are being transported in conveying direction from chamber to chamber, in that the laundry items need no longer be passed through openings in the chamber walls (the transport channel) but, rather, are conveyed over a blade along the path of the worm or screw.
  • the laundry items and the bath are lifted by the blade-like entrainment device and again dropped from the top into the same washing chamber.
  • the fabric of the laundry items is perfused by the treatment fluid because said fluid moves ahead of this fabric and the laundry subsequently drops into the treatment fluid.
  • the fibers of the fabric are stretched and then compressed again, thus promoting perfusion of the fabric.
  • the continuous washing machine in accordance with the invention may advantageously be selectively operated either in a rotating or also in a back-and-forth pivoting manner.
  • the laundry In conveying mode of the continuous washing machine in accordance with the invention the laundry is transported by means of the screw in conveying direction, on the one hand, and first lifted by means of the entrainment device and then dropped again by the entrainment device during further rotation of the drum, on the other hand.
  • the treatment fluid may take the same path.
  • FIG. 1 a schematic partial side elevation of a continuous washing machine in accordance with the invention
  • FIG. 2 a sectional view of the continuous washing machine in accordance with FIG. 1 , perpendicular to the illustration of FIG. 1 ;
  • FIGS. 3 a through 3 e schematic sectional views of the continuous washing machine in accordance with FIG. 1 , in different angular positions in washing mode;
  • FIGS. 4 a through 4 e schematic sectional views of the continuous washing machine in accordance with FIG. 1 , in different angular positions in conveying mode;
  • FIG. 5 another schematic sectional view of the continuous washing machine in accordance with FIG. 1 , this showing the ribs on the metal entrainment baffle, on the screw as well as on the inside of the drum.
  • washing mode “washing region,” “washing chamber,” etc.
  • these may be presumed to be treatments that usually occur in a washing machine of the type concerned here, namely, in particular, also rinsing and, optionally, also conditioning, so that, in particular, a “rinsing mode,” “rinsing region,” “rinsing chamber,” etc. are to be included.
  • a continuous washing machine that is not shown in detail comprises a cylindrical drum 2 or an interior drum 2 that can be rotated about its longitudinal axis 4 by means of driving means that are known per se and are thus not specifically illustrated, i.e., in one of the two possible driving directions.
  • Located inside the drum 2 is a worm 6 or a screw 6 which, e.g., may consist of canted sheet metal and whose exterior helical exterior edge 8 is joined, in particular welded, to the interior wall of the drum 2 .
  • the screw 6 has helical cants or reinforcement ribs that are not specifically illustrated here and that extend in radial direction.
  • the arrangement of the rotatably supported drum 2 including the screw 6 that is located therein and non-rotationally connected to the drum 2 corresponds to the arrangement of a screw-tube conveyor.
  • a feeding hopper for example, is used for loading the laundry items to be treated into the drum 2 in a not specifically illustrated manner from the left, referring to the illustration in accordance with FIG. 1 ; and, in a likewise un-illustrated manner, the treated laundry items are moved out of the continuous washing machine to the right, referring to the illustration in accordance with FIG. 1 , for example, by means of an output slide; and, subsequently, said laundry items are passed on to a water-extracting device, for example, namely a water-extracting press, for example.
  • a water-extracting device for example, namely a water-extracting press, for example.
  • conveying mode the laundry items are transported through the drum 2 in the general conveying direction A by rotation of the drum 2 , including the screw 6 , in the direction of rotation B in a counterclockwise direction.
  • a space disposed to act as a washing chamber 12 is respectively defined by two opposing screw sections 10 of the screw 6 .
  • an entrainment device 14 being configured as a metal entrainment baffle 14 that, among other things, is disposed to carry along the laundry items when the drum 2 and the screw 6 are being rotated in washing mode, i.e., lift said laundry items, etc; see further below.
  • Each metal entrainment baffle 14 is laterally joined, in particular welded, to the adjacent screw sections 10 in a fluid-tight manner and extends from an approximately central position between the longitudinal axis 4 and the interior wall of the drum 2 in outward direction toward the interior wall of the drum 2 , to which said baffle is also joined, in particular welded, in a fluid-tight manner.
  • Each metal entrainment baffle 14 is curved spiral-like about the longitudinal axis 4 , as is particularly obvious from FIG. 2 , whereby the radius of curvature relative to the longitudinal axis 4 increases from the inside toward the outside. All metal entrainment baffles 14 are aligned inside the drum 2 , preferably in the same direction of orientation.
  • the entrainment baffles 14 prevent a transport of the laundry items (and the treatment fluid) along the longitudinal axis 4 as would be the case in a screw-tube conveyer. Rather, the laundry items, along with the treatment fluid, are held in one and the same washing chamber 12 during the entire washing cycle while the drum continuously rotates in the direction of rotation C.
  • the laundry When, upon completion of a washing cycle, the direction of rotation of the drum 2 is reversed and the drum 2 , together with the screw 6 , is driven in the direction of rotation B, the laundry, optionally together with the treatment fluid, is conveyed in longitudinal direction 4 of the drum from one washing chamber 12 to the adjacent washing chamber 12 , as corresponds to the usual operation of a screw-tube conveyor.
  • the laundry items are increasingly lifted by means of the entrainment baffle 14 during the rotation and finally drop over the free edge of the entrainment baffle 14 downward to the bottom of that washing chamber 12 which is adjacent to the previous, original washing chamber 12 .
  • FIGS. 3 a through 3 e show various phases of the washing mode or conveying mode, respectively in 90° steps of rotation of the drum 2 :
  • the drum 2 In washing mode in accordance with FIGS. 3 a through 3 e , the drum 2 is continuously driven in the direction of rotation C. Assumed in this case is the situation in accordance with FIG. 3 a .
  • the treatment fluid 20 has collected in the chamber 12 on the bottom of the drum 2 , the laundry items 22 are lying or floating in the treatment fluid 20 .
  • the metal entrainment baffle 14 is essentially located above the treatment fluid 20 and the laundry items 22 , respectively.
  • the treatment fluid 20 arrives in the space 16 between the metal entrainment baffle 14 and the opposing drum wall, i.e., in other words, the metal entrainment baffle 14 slides itself over the treatment fluid 20 , along with the laundry items 22 .
  • the drum 2 is rotated a single time by 360° in the direction of rotation B.
  • the starting point in FIG. 4 a may be, for example, the angular position of the drum 2 that corresponds to the position of FIG. 3 a or 3 e .
  • the treatment fluid 20 has collected in the chamber 12 on the bottom of the drum 2 , the laundry items 22 are lying or floating in the treatment fluid 20 , and the metal entrainment baffle 14 is essentially located above the treatment fluid 20 and the laundry items 22 , respectively.
  • the metal entrainment baffle 14 pivots in the selected direction of rotation and subsequently said baffle's radially outward end pivots downward until it comes into contact with the treatment fluid 20 and the laundry items 22 therein and increasingly lifts said laundry items; see FIG. 4 c.
  • a conveying cycle is thus completed; the laundry items 22 , along with the associate treatment fluid 20 , have been conveyed in conveying direction A from one washing chamber 12 into the adjacent washing chamber 12 , and a new washing cycle may start.
  • one rib 18 (per washing chamber 12 ) is provided on the metal entrainment baffle 14 , said rib extending essentially in longitudinal direction 4 of the drum 2 ;
  • one or more, in the case of the exemplary embodiment, three ribs 24 are provided on the interior wall of the drum 2 , said ribs also extending essentially in longitudinal direction 4 of the drum; and a plurality of cants 26 of the screw 6 extending radially outward in an approximately star-like manner are provided.
  • the at least one rib 18 on the metal entrainment baffle 14 is located in the region of the space 16 (see FIG. 3 a ) in order to permit the laundry items 22 to slide more gradually off the metal entrainment baffle 14 or to be pulled apart more, as a result of which, during the washing process, an increased degree of stretching and compressing of the laundry is ensured, thus further increasing the washing quality.
  • the rib 18 may be placed on the entrainment baffle 14 , e.g., welded thereto or canted into the metal entrainment baffle 14 .
  • the preferably several ribs 24 on the interior wall of the drum 2 are provided, in particular, for the purpose of generating even more washing mechanics, in particular also in the case of pivoting washing, i.e., in the case, in which the drum 2 of the continuous washing machine performs a back-and-forth pivoting motion in washing mode.
  • the ribs 24 may be welded, for example to the interior wall of the drum 2 .
  • the radially outward extending screw cants 26 on the screw 6 act to stiffen and stabilize the design, on the one hand, and to further intensify the washing mechanics, on the other hand.
